TYPE-WRITING MACHINE.

T0 all whom it may Concern:

Be it known that I, BURNIIAM C. STICK- NEY, a citizen of the UnitedStates, residing cially to those of the frontstrike class.

My invention consists in certain combinations of devices, features ofconstructions, and arrangements of parts, which will be hereinafterdescribed and particularly pointed out in the'concluding claims, and isa division of my application No. 163,704, filed June 30, 1903.

The principal feature covered herein is the connection between thekey-operated uni'- versal bar on the main framework of the machine, andthe carriage, which shifts up and down, said connection being a train ofescapement mechanism extending fromthe universal bar to the carriage,aiid including members which are connected at a point which coincides withthe axis about which the carriage shifts up and down, so that thelshifted.

In the drawings `forming part of this specification, Figure 1 is alongitudinal sectional elevation of a front strike writing machineembodying my improvements; one

type action being shown in 'printing posi! tion. Fig. 2 is a front viewofthe machine, showing tlievcarriage tilted up to expose the undersidethereof, and give access to the carriagespring tension lad] ustingdevices.

The framework of the machine comprises side walls and rear walls forminga base l,

and a depressed top plate 3. Forwardly extending type bars et arepivoted at their rear Original application led .Tune 30, 1903, SerialNo. 163,704. Divdediand this application 1912. serial No. 724,540.

latter being uppermost when the type-bar is in printing position,although this relation may lhe reversed within the scope .of certainfeatures of my improvements, and the typebars may be otherwise mounted.The typebars-may be Operated by any suitable means, as for. instancepull-links 11, extending rearwardly and downwardly from the type-bars,

pendent levers 12 connected between their ends at 13 to said links, -ahorizontal rod 14 whereon said levers arefulcruined at their 4upperends,v horizontal links l5 connected at 16 to the' lower ends of saidlevers. and extending forwardly, and key-bearing bellcranks fulcrumedupon a transverse rod 17 and lia-ving pendent arms 1S connected at 19 tosaid linksl, and forwardly-extending arms 20 bearing the lkeys 21.Returning springs as 22 may be provided for the type actions.

The platenj may be mounted by' means of an axle 25 upona carriage 26,which may be of any suitable construction, but preferably -`comprisesupper and lower bars 27 and 28, the'former provided in its undersidewith a longitudinal groove 29, and thel latter in its upnerside with alongitudinal groove 30; these bars being connected at their ends byupright bars .31 and 32 formed integral therewith. An integral plate orbar 33 projects forwardly from said connected bars, and at its ends isformed with upright arms 3st and 35 in which th'e platen axle 25 isjournaled. Embraced by Athe grooved vbars 27l and 28 is a rail 3G, seton edge and provided in its top and bottom edges with grooves 37 and 3S,which arev provided with bearing balls 39, whereon the carriage runs.Said grooved rail 36 forms part of a movable frame, whereby -the papercarriage -is enablednot only to run in letter-feeding direction, butalso to move vin a direction transverse thereto. in addition to saidrail (which may be Otherwise formed in some cases) rearwardly extendingintegral arms 65, which are united at their forward ends by said rail,and a bar G6, which unites said arr-.is between their ends and isintegral therewith. Said arms are extended rearwardly from saidlbar 66,forming ears 67 and 68, which are hinged by pintles 69 in bosses 70 and71 which pro- This frame comprises,l

ject inwardly from ythe tops of the side walls of the framework 1. Thecarriage togetherwith its supporti-'ng' frame may be swung oritilted up'about said hinges, so as and cooperating with a 'rack 106 on thecarriage; said feeding'mecha'nism comprising upright detent and feedingdogs 107 and 108, the latter normally in engagement with the rack. Therack is mounted upon the rear ends of hinged arms 109 and 110, the

` latter being prolonged forwardly of its hinge and provided with adepressible carriage-release key 111. The dogs are mounted upon one endof a rock-shaft 112, jour-l naled in a boss 113 formed upon an arm 114directed upwardly and forwardly from the shifter-frame bar 66; and saidshaft at itsother end is provided withan operating arm 115, which `atits rear end lis pivoted at 116 to a pendent link 117, whereby the armis y operated; said pivot 116 being normally substantially coincidentwith the axis of the hinge 69 of the carriage-supporting frame, so thatthe operation of the escapement mechanism is rsubstantially the samewhether the frame is in normal position or shifted up to write capitalletters. At its lower end said link is pivoted at 118 to the forward endof a rocker-arm 119, which projects forwardly from ahorizontaltransverse rock-shaft 120. A universal bar 121 is mounted upon the ktopsof a .pair of arms 122 which rise from said rock-shaft, and lies in rearof the levers 12 of thev type-actions, so

as to be operated thereby, as at Fig. 1; the

described'universal-bar frame being provided with a returning spring123.

The carriage feeding mechanism of a typewritin'g machine comprises auniversal bar such as 121, and a carriage rack such as 106 andintervening connections In this instance, the connections comprise arms122, 119, link 117, ann-115, shaft 112, and dogs 107 and 108. In thistrain of mechanism, one of the working joints, namely 116, is normallyabout in line with the axis of the hinge 69 upon which the frame 65swings up. Hence the type keys 21, which are on the stationary mainframe of the machine, are enabled to control the operation of theeseapement dogs 107 V'and 108 whether the shift frame 36, 65, 67 isup ordown. So long as this result is obtained, it is not ma- -terial whetherlthe joint 116 or some other joint in the carriage feeding train iscoinci dent with the axis 69. It will be noticed that the path ofmovement of the p ivotf116 may intersect the axis of the hinge 69,

whereby the link 117 will have the same effect on the escapement dogs107 and 108 iat all printing positions ofthe platen. 'f

The 'carriage may be propelled by a spring-barrel 127, lyinghorizontally and mounted upon the lower end of a. stud l28 dependingfrom the hinged carriage-frame; a strap 129 being attached to the barreland caught upon a hook 130 upon the carriage bar 28. A ratchet wheel 131and pallet 132 are provided for adjusting the tension of the spring, theformer having a finger-piece 133 and the latter a finger-piece 134, bothof which in normal position project downwardly, the ratchet-wheel andpallet being mounted below the spring barrel. When the carriage istilted up, as at Fig. 2, access is givenl to the ratchet wheel andpallet, thus facilitating the adjustment of the spring. By mounting thespring barrel and the carriage-feeding mechanism upon the hinged frame,the latter is permitted to swing freely up and down,'without liabilityof deranging the carriage-controlling devices, which always preservetheir proper relation to the carriage. j Preferably advantage is alsotaken of the hinging of the'carriage-sup port, to enable'the latter tobe shifted up and down to enable different types to print. Normally thecarriage and platen are in the lowermost position, as in full lines at10i l, thereby enabling 'the lower-case types 9 to print; while byelevating ythe carriage and platen, as indicated by the dotted circle 7,the upper case types 10 are enabled to print.

The downward movement of the carriage is limited by an adjustable stop136, threaded forwardly through an arm 137 cast upon the rear wall of'the machine framing; arm 7 8 of the hinged carriage supporting framebeing prolonged, as at 138, to bear against said adjustable stop.

A shift-lever 139, bearing a key 140, projects forwardly and upwardlyfrom a transverse horizontal rock-shaft 141, journaled in the side wallsof the base; and about midway of its length said shaft is provided withanvupright arm 142, from which extends rearwardly a link 143, whose rearend has a sliding bearing at 144 in the upper portion of said cast arm137. Said link is 'provided with a lug 145, adapted to catch a.

nib 146 formed-upon a hook-shaped stop 147 pivoted at 148 tothe lowerportion of said arm 78. By depressing the shift key, the shaft 141 andarm 142 thereon are rocked, pulling forwardly the link 143, and by meansof the lug 145 and nib 146 swinging the stop down, until the'said nib isarrested by a stop pin 149. Continued movement of the key, rock-shaft,arm and link then, swings the frame arm 78 forwardly and the frame andcarriage upwardly about the hinge 69, until the parts are arrested, withthe platen in the dotted line position,

by the contact of the hook-stop 147 wit-hf said frame, so as to bebrought into an acthe upper endof said cast arm 137 (which of course maybe provided with ,an adjustable stop, if desired.) After the capitaltype or types are written, the shift key is returned to normal positionby a sprlng 150, while the hinged frame and carriage return i bygravity. A spring 151 lifts the hook-stop 147 until it is-again clearofthe upperpend of said cast arm 137, so that it may not contacttherewith to interfere with the upward tilting movement of the carriageto the Fig. 2 position. During such tilting movement,

the arm 78 and parts thereon are swung forf wardly away from theircooperatingI partsf mounted in the machine base; so that at any time thecarriage'may be given either a limited movement for writing capitals ora f movement to expose the underside tilting thereof.

v Wide variations may be resorted to within the scope of my invention,and portions of my improvements may be used without others.

Having thus described my invention, I claim:
